Socket pipe processing device and manufacturing method for socket pipe

Abstract

A socket pipe processing device and a manufacturing method for the socket pipe. A right-right angle bracket is fixed to the right side of a workbench, and a left-right angle bracket is fixed to the left side of the workbench. An upper side mold core slider bar is arranged between the front part to the rear part of the upper side of four corners among the left-right angle bracket and the right-right angle bracket, and a lower side mold core slider bar is arranged between the front part to the rear part of the lower side of four corners among the left-right angle bracket and the right-right angle bracket, and a right mold core fixing plate and a left mold core fixing plate are respectively movably fixed thereon. The left mold core fixing plate and the right mold core fixing plate are connected with the right-right angle bracket and the left-right angle bracket via a right cylinder and a left cylinder. A technical process comprises: pushing in a mold core after closing the mold, bi-extruding a molten plastic material by a twin-screw extruder, and after the plastic material fills a mold cavity, water cooling for molding, is employed. When a socket type winding pipe is welded with the socket pipe, the weld strength is maintained consistent, coaxiality deviation of underground drainage pipe system is small, achieving long-term and reliable operation, effectively preventing the deformation and cracking of the combined drainage pipe system which causes the occurrence of chronic water seepage to contaminate groundwater.

Description

technical field [0001] The processing device of the socket tube and the manufacturing method thereof of the present invention relate to the technical field of design and manufacture of socket-type plastic tubes, and are applied to the manufacture of socket tubes. Background technique [0002] Existing drainage projects generally use socket-type winding pipes with high bearing strength as the pipe material of the sewage pipes, which are buried underground. The connection methods of socket-type winding pipes: electric hot-melt belt hot-melt connection, clamp connection, heat shrink connection, flange connection, etc., some connection methods have better strength, complicated process, and difficult connection; The method is not suitable for working with water; but most of them are due to the manufacturing of the connecting socket pipe, resulting in uneven thickness, which is easy to cause deformation of the socket pipe, especially the socket-type winding pipe and the socket pip...
